Landlords were greedy, they should rot in he** and on and on....

I get not every situation is cut and dry.  

Most investors in your position go with hard money loans to get in on a deal with the cash is dry, but here you have to be careful about your numbers. 

New roof and car port, all new water pipes, dry basement work, clean out of junk left, painting,  new appliances, siding replaced in eves and rain gutters added, new lights in some rooms, new floors in 1/2 the house, new HVAC. 

I have 2 two story properties adjacent to each other that are currently vacant and uninhabitable, the roof is collapsing and the wooden beams are rotting etc.

In a dry climate area like Denver mold should be relatively easy to eliminate.

The inspection came back with some dry rot issues along with water intrusion effecting the siding and may need a full residing / recladding of the building. 

While the water issue may be able to be solved, keep looking for a dry property.

Tenant will immediately act to identify and remove/clean up the source of any such odors and to ventilate the rental unit or otherwise remove the foul odor upon discovery of it.General --Walls: should be clean, free of dirt, grease, holes, cobwebs, and fingerprints.Floors: should be clean, clear, dry and free of hazards.Windows: should be clean and not nailed shut.

I like the Smartcore from Lowe's - 100% vinyl so it goes anywhere wet or dry, already has underlayment attached, good wear layer (12 mil or higher), good realistic look for flooring.
